o. sANN MINE CAR 3 Shee'cs--Shee'cv 3 Filed April 20, 1928 raam-aa oa., as, reaso istante ,espinacas-ana apra so, ieee. serian no. avana rlhis invention relates to cars and, while not limited thereto, relates more particularly to that class of cars used in and around industrial plants and mines, and has for its object the provision of a car hating a maximum oi' cubical capacity c-oupledgvvith .a relatively low height so as to beparticiilarly adapted for use in mines having low head room.

Another object is to provide a car having a novel construction -whereby the car body is mounted directly on the axles Without the use of the customa rame'or bolster.

A further object is to provide a novel construction whereby the stresses and strains delivered to the lends et the cars, due to the bumping oi the cars together and pulling will be distributed from end to end of the cars and to the several carsoit a train instead of being absorbed in the car body.

ln the drawings-- Figure 1 is a plan view of a mine car con-- structed in accordance with this'invention.

Figure 2 is a side elevation thereof.

Figure 3 is a longitudinal sectional elevation taken on the line llllll of Figure 1.

Figure d is a transverse sectional elevation' taken on the line lV-lV of Figure 2.

Figure 5 is an enlarged ragmentary sectional view illustrating the details of the axle construction and mounting.

Figure '6 is an enlarged fragmentary detail view of the portion ci the car body having the axle attached thereto.

Figure 7 is a :fragmentary sectional detail oi a portion of a modied form of axle in which the spindle is formed separately from. the axle body. s

Referring more particularly to the draw ings, the letter A designates the car body as a whole which is composed of metal. rlhe body A has a lower portion composed of a bottom Wall 2 and vertical side Wall portions 3 formed integral, and an upper portion consisting of side Wall extension portions composed of vertical side Wall portions d joined to and forming an extension of the verticalside Walls 8, outwardly projecting 'horizontal extension wall portions vabnd outer vertical side Walll portions 6. The Wall portions 4, 5 and 6 are all formed integral and, since the Walls d are joined or secured to the side Walls 3, the complete sides and ends of the body form a unita self-supporting structure.

gne end of the body is closed by a rigid or lined end Wall i8, and the other end of the body is closed by a swinging gate 9 supported by hinge-members l() pivotally secured to the side Wall portions 6 ot the car body, as at l2.

The upper portions oi the car body, composed of Walls d, 5 and 6, are cut away to iorm wheel clearance recesses and raised cap members 13 are secured over said recesses to form a continuous side Wall.

ihe car body A is mounted directly on a pair of U-shaped axle members 14 Without a bolster or under-frame. rlbe axle members ld are substantially -shaped and extend across the underside of the bottom Wall 2 of the body and up along the outside oi each side of the car body into the Wheel clearance recesses and have their upper ends projectingk outward ly under the top Wall of the cap members 13. rlhe axle members are secured to the bottom and sides-of the car body and serve as stidening members for the body.

The axle membersy 14 vmay be formed by forging or casting, as desired, and are provided intermediate the ends of .their side portions, which parallel the sides of the car body, with Wheel carrying spindles y16. When the axles 1d are formed of cast metal, the spindles v16S-are formed integral therewith, as shown in Figure 5, While when the axles are forged,

the side portions are provided with tapered apertures 17 and the spindles 16 are formed separately and secured in the apertures 17 by upsetting or riveting the inner end 17a as shown in Figure 7.

v The body of the car is provided with Wooden bumper blocks 20 at each end of the bottom Wall 2 which project materially beyond the ends of the side walls 3 of the car.

'lhe rear end of the bumperblocl; 20is sup- I ported and backed up by a Z bar member 21 secured to the bottom 2 of the car. An inclined plate 22 is secured to the bottom plate 2 oi 4the car and extends upwardly and over the top of the bumper biockso as to facilitate the endwise movement of the material in the car when the car is dumped.

A relatively heavy reeniorcin bar 23 eX- tends over the top of the bumper loclr` 20 and l and forward end of the "er blockandv under the end of the bottom o the car body and is secured thereto; IThrough-bolts 26, or

rivets, extend through the bumper casting'2d,

'car along the upper i the next adjacent reenforcing bar 23,' bumper block 2O and ear bottom 2, so as to tie all of such parts together as a unit.

A tie-bar extends from end to end of the or to face of the bottom wall 2, and is secured to t e wall 2 and to the axle'members 14 and also to the reenforcing bars 23 at each end of the car. The ends of thebar 25 are bent upwardly and extend outwardl parallel with and in spaced relation with t e upper faces of the bumper blocks.

The ace between the ends of the tie-bar 25 and :he bumper castin s 24 form receiving recesses for the st andar coupling links 27,

andthe tie-bar ends, bumper castin s and bumper blocks are providedwith alin apertures to receive a coupling pin 28.

By providing the tie-bar 25, the strains and stresses delivered to the ends of the cars are delivered throughout the length of the car to car, and not absorbed in the car body as would'be the case if the bumper. blocks were sup orted by the car body alone.

The axle mem rs 14, by their novel sha e and mounting, serve to stiien the car bo y and also provide for a car construction having a minimum of overall height. i

While I vhave shown and described certain `specific embodiments of my invention, it will be understood that I do not wish to be limited be to said bumper blocks and bumper castings.

thereto since various modifications may made without de arting'from the scope thereof as defined intl! e appended claims. I claim- Y 1.
